THOMAS J. CAHILL, OF PHILADELPHIA, PENNSYLVANIA.

AERIAL BOMB.

Application filed May 8,

To all whom it may concern:

Be it known that I, vTHoMAs J. CAHILL, a citizen of the United States,and a resident of Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented a new and Improved Aerial Bomb, of whichthe following is a full, clear, and exact description.

This invention relates to improvements in aerial bombs for aeronauticaluse.

The primary object of the present invention is to provide a bomb of thecharacter described housing a plurality of small arm projectiles whichare adapted to be simultaneously discharged therefrom by the impact ofsuitable detonator upon its contact with the ground.

In constructing this bomb, particular attention has been directed to thelightness of its structure, an essential feature in order to render thesame useful for aeronautical work.

A further object resides in the provision of bomb body, so constructedas to present a solid outer surface which may be treated with a waterproof coating thereby rendering it impervious to moisture and dampnessor other destructive elements.

Another important object residesin the provision of a bomb which can beconstructed from inexpensive readily attainable material and which isquickly and easily assembled thereby reducing the time and laborrequired for its production.

With the above recited and other objects in mind, some of which will beobvious from the following detailed description and appended claim,reference is had to the ac companying drawings which are a part of thisapplication, and in which;

Figure 1 is a perspective view..partly in section.

Figure 2 is a horizontal sectional view therethrough.

Referring to the drawings by characters of reference which denote likeparts throughout the several views thereof, the bomb body is constructedpreferably of a pair of semicylindrical wooden sections designated bythe numerals 10 and,11, having longitudinal dovetail tongues and grooves12 and 13 in their confronting Walls which are adapted to mate andco-act to secure the sections together. The sections are provided with aplurality of radial circular recesses 14 ex tending from their innersurfaces to a point Specification of Letters Patent.

slightly within their outer surfaces and said recesses are lined withmetallic sleeves or bushings 15,,constituting chamber 16 for thereception of bullets or projectiles 17. The closed ends of the recessesare lined with a felt disk or wad 18 and a similar wad 19 covers theinner end of the projectile. The opposite ends of the body sections 10and 11 are threaded as at 20 to receive the closures or heads 21 and22'having the conical portions 23. The apex of said conical portions areapertured and a shaft 24 is threaded in to the aperture of the upperhead 21. The upper free end of the shaft is provided with radial blades25 which constitute a stabilizing vane to effect vertical gravitation ofthe bomb upon its release from the aircraft. The aperture of the lowerhead is adapted to receive the upper end of a rod 26 which carries asuitable detonator 27. The lower exposed extremity of said rod isprovided with an enlarged impactfoot 28 which effects an upward movementof the rod upon contact with the ground or any other solid object. Acircular core 29 preferably of wood is positioned concentrically withinthe body and is maintained in this position by means of a cylindricalshell 30 having diametrically disposed radial fins 31 which bear againstthe inner surfaces of the body sections. The lower extremity 23 of thecore is conical and is provided with a metallic point 33 which normallyrests lightly on the detonator 27, said metallic point being de signedto prime the detonator when the foot 28 contacts with the ground andforces the same into contact therewith. The explosive charge 34 isfilled in the open space between the core and the body and when ignitedby the detonator effects the radial projection of the bullets from thebody through the sides thereof. The rod 26 isof a suflicient length toeffect the explosion of the charge when the bomb body is at anappropriate dlstance from the ground to obtain the best results. Afterthe bomb is assembled the same is coated with a water proof coating torender the same impervious to moisture or dampness. If desired the rod26 may be detachably associated with the detonator in order that thesame may be removed to minimize the danger of an accidental explosionduring its transportation.

While there has been illustrated and described a sin 1e and preferredembodiment of the inventlon, no limitation is necessarlly made to theprecise details of construction as obvious changes and modificationsfalling within the scope of the appended claim, may be resorted to whenfound expedient.

Having thus described my invention, I claim as new and desireto secureby Letters Patent In an aerial bomb, a hollow cylindrical wooden bodyportion having a plurality of radially extending bores communicatingwith its interior and terminating short of its outer periphery, wherebyto provide an integral frangible exterior shell, metal bushings in thebores, projectiles located entirely within the bushings, pads within'thebushings covering the inner and outer ends of the projectiles, and theinterior of said body adapted to receive a common charge for proje'ctingsaid projectiles radially through the franglble walls of the of thecharge.
